rockchip: rk3588-rock-5b: Add USB-C controller to u-boot.dtsi
Add USB-C controller (fusb302), which will be used by U-Boot to
initialize USB-PD. This is needed, because USB-PD communication
must happen within 5 seconds after the USB-C connector got plugged.
On my Rock 5B it often takes 5 seconds to jump to the Linux binary,
so it must happen before Linux is initialized.
This adds the DT node to the U-Boot specific file, since the Linux
kernel DT currently does not describe it to avoid a system reset.
The plan is to add it to the Linux DT with status = 'fail' and then
let U-Boot mark it as status = 'okay' if it properly dealt with
early USB-PD initialization. Until the Kernel DT has the node, let's
add it in U-Boot to get things going.
